deep mastering has revolutionized the field of scientific imaging, providing practical affected person prognosis competencies. A current example is deep studying for Magnetic Resonance imaging (MRI) acquisition, reconstruction, segmentation, and interpretation. Deep mastering-primarily based strategies leverage convolutional neural networks (CNNs) to automatically classify and section not unusual disease areas in MRI scans, allowing particular and correct prognosis. Those computerized strategies can potentially conquer the bottleneck of the complex work-intensive guide segmentation and visualization procedure. Moreover, they can provide an extra complete assessment of complex sicknesses. Through incorporating both the semantic and spatial information of image information, the overall performance of deep-gaining knowledge of-based totally structures for MRI evaluation has dramatically progressed. Moreover, CNN-based total MRI segmentation has proven promise in targeted and effective remedies for numerous diseases, including mind tumors, stroke, and dementia. The demonstration of superior effects in segmentation and classification tasks, in terms of accuracy and efficiency, shows the potential of deep learning-based techniques as an effective device within the automation of MRI analysis. © 2024 IEEE.

Mixed reality head-mounted displays (mxdR-HMD) have the ability to visualize volumetric medical imaging data in holograms to provide a full 3D perception of volumetric information. An effective user interface, however, has yet to be thoroughly studied. Tangible user interfaces (TUIs) enable interaction with holograms through objects that possess physical properties, which indicate their usage, and enable manipulation across multiple degrees of freedom. The main technological challenge in enabling TUIs on mxdR-HMDs, which are inherently limited in computational resources, is tracking the physical object in a timely and accurate manner and achieving seamless TUI integration. We introduce a markerless TUI employing a handheld planar object (PO) to interact with medical holograms, termed the mxdR hologram slicer (mxdR-HS). Our mxdR-HS enables users to slice the medical hologram to inspect regions of interest in real-time, integrate complementary data, and make annotations. We implemented our mxdR-HS on Microsoft HoloLens 1 – a computationally modest mxdR-HMD. We benchmarked our mxdR-HS against well-known tracking methods in various mxdR usage scenarios. Our mxdR-HS demonstrated a reduction in computational latency but with a marginal decline in tracking accuracy when compared to two marker-based methods. When compared to seven markerless tracking methods, our mxdR-HS improved in both latency and accuracy. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Fiblets for Real-Time Rendering of Massive Brain Tractograms

computer graphics FORUM 2022年第2期41卷 447-460页

We present a method to render massive brain tractograms in real time. Tractograms model the white matter architecture of the human brain using millions of 3D polylines (fibers), summing up to billions of segments. They are used by neurosurgeons before surgery as well as by researchers to better understand the brain. A typical raw dataset for a single brain represents dozens of gigabytes of data, preventing their interactive rendering. We address this challenge with a new GPU mesh shader pipeline based on a decomposition of the fiber set into compressed local representations that we call fiblets. Their spatial coherence is used at runtime to efficiently cull hidden geometry at the task shader stage while synthesizing the visible ones as polyline meshlets in a warp-scale parallel fashion at the mesh shader stage. As a result, our pipeline can feed a standard deferred shading engine to visualize the mesostructures of the brain with various classical rendering techniques, as well as simple interaction primitives. We demonstrate that our algorithm provides real-time framerates on very large tractograms that were out of reach for previous methods while offering a fiber-level granularity in both rendering and interaction.

Off-road heavy machinery such as snow groomers or excavators, often operate in low-light and hazardous environments. In this work, we explore the development of an intelligent camera-spotlight system with automatic and manual control to illuminate points of interest, such as obstacles or individuals at risk. We implement a prototype as proof of concept and integrate our workflow using a standard lighting protocol and a single-board computer. The presented calibration of the camera and spotlight ensures high precision in the desired use cases. In addition to testing the prototype on a real snow groomer, we evaluated its performance in terms of accuracy and repeatability. Overall, we showcase the usability of a commercially available spotlight in the context of spatial augmented reality in heavy machinery applications. © 2024 University of West Bohemia.

Our lab holds a workshop using computers to create electroacoustic music (EAM) for a variety of inexperienced people. Since EAM is positioned as an extension of contemporary music, which has a large philosophical component, it has not gained as many creators and listeners as popular music. The reason for this may be that, compared to music meant for entertainment, both the structure in music theory and the concepts in expressive practice create the impression among many people that EAMis difficult to understand. However, we observed that numerous people enjoy creating EAMin workshops. This may be because EAM is created not by following the rules of ordinary music theory, but by producing a montage of sound materials formed from fragments of recorded sounds along a computer timeline, allowing the listener to hear a near-perfect acoustic representation in real time through intuitive manipulation. Through our creative method, we taught participants to capture their impressions of fragmented acoustic materials using metaphorical adjective pairs such as 'high-low' and 'hard-soft' and to maintain the intensity of the contrast between them. This study is based on an analysis of the works created in university courses that share the same teaching techniques as our workshops. The analytical procedure of the present study was as follows: (1) We selected an 'excellent' completed piece of music. (2) We individually extracted the acoustic materials that made up the piece. (3) We used pairwise comparison to examine the participants' impressions of all acoustic materials used in the given piece. (4) We carried out an analysis to determine whether the original piece maintained a high degree of contrast in the impression of the acoustic materials, thereby validating our instructional technique, which we empirically derived from past workshops. © 2023 Proceedings of the international conferences on Interfaces and Human computer Interaction 2023, IHCI 2023;computer graphics, Visualiza

To address the critical challenge of pupil segmentation accuracy in medical image analysis, this paper proposes an innovative pupil segmentation method based on an enhanced TransUNet deep neural network. The proposed architecture introduces three key improvements: a novel multi-kernel self-selective attention mechanism that optimizes local feature extraction through weighted fusion of different convolution modules;a modified cross-attention Transformer that enables efficient parallel processing of spatial information in both horizontal and vertical dimensions;and an advanced feature fusion module that effectively integrates global and local information through multi-scale feature weighting. Extensive experiments on the OpenEDS dataset demonstrate the method's superior performance, achieving state-of-the-art results with average precision of 97.7%, average recall of 97.41%, and average Dice coefficient of 98.15%. These significant improvements in segmentation accuracy not only advance the field of medical image analysis but also provide a robust foundation for applications in ophthalmological diagnosis, human-computer interaction, and cognitive science research. The proposed methodology offers valuable insights into designing efficient attention mechanisms for medical image segmentation tasks, contributing to both theoretical understanding and practical applications in healthcare imaging systems. © 2025 SPIE.
